writes "I've been contributing and releasing open-source projects for a number of years now, and managed to stay (mostly) clear of conflict. One of my projects BSOD(roid) have been available on the Android Market for nearly a year. Last night, I've received a email asking me to rename my product because it infringes on the trademark ROID. This trademark has been filled nearly six month after my project was on the market. The two projects are completely unrelated and do not compete. Renaming the project is not the issue here. Responding to mindless corporate bullying is. I'm curious to know if this happened to other slashdotter and what suggestions you may have."
